PLAYLIST plays wrong song

If your playing a song in your "All Music" playlist, and you have a look at another playlist by pressing back or forward. When you come back to the playlist where your song is playing and it finishes or you click next, it just goes to the first song in the list. Instead of going to the next song like it should.
And you have to scroll down trying to find your spot again, and if you have a big list it takes ages to find your spot again.

Also, will that fix take into account for when your coming out of a searched playlist into your All Music playlist, so when you hit next, it plays the song that comes after the one you searched for, but in the all music playlist, kinda like winamp?
